Nukio — Save & Learn

About

Turn the web into things you actually learn and remember.

Nukio lets you save useful pages, highlights, PDFs and videos while you browse, then understand them in place with an AI side panel that knows what you are looking at.

Save what matters:

Save the current page from the toolbar.
Select text and save it as a note or highlight.
Save YouTube, Vimeo and Spotify pages for later learning.
Use the right-click menu when it is faster.
Understand without leaving the page:

Select text and choose Explain for a concise breakdown.
Ask questions about the current page, PDF or video.
See related Nukio concepts directly in chat.
Pronounce concepts, read AI answers aloud and translate into your native language.
Keep learning in Nukio:

Saved content appears in your Nukio library.
Extracted concepts and summaries help you continue from the web or app.
Concepts can be saved to your learning queue for review.
